It requires the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection.

It can be used for a long time without being broken, which is very convenient for people to observe the situation in the distribution box in real time, bringing better use prospects.

[0004] However, in the implementation of relevant technologies, it was found that the box-type fixed closed distribution box of the above-mentioned design has the following problems: the above-mentioned technical scheme adopts a high-temperature resistant glass window through the convenient observation window mechanism, which has excellent heat and high temperature resistance and can be used for a long time without being broken. It is very convenient for people to observe the situation inside the distribution box in real time, and there is no need to open the box door every time. The sealing is good.
